Medical weed seeds

A guide to buying cannabis seeds

The first couple months of the year is a great time to start planning your cannabis garden to get a head start on the outdoor growing season, which roughly runs from March to November, depending on where you live.

Navigating the cannabis seed market can be challenging when states have different degrees of legality. This guide will answer your questions on buying seeds so you can be on your way to growing your own cannabis.

Is it legal to buy marijuana seeds?

Marijuana seeds are considered a cannabis product just like flower, edibles, and concentrates. Their legality depends on which state you live in. People living in states with adult-use legalization can buy, produce, and sell seeds within their own state, but seeds can’t cross state lines. People living in states with medical marijuana legalization can only buy seeds if they have a medical card.

Seed banks exist outside of the US and can sell them for “souvenir purposes,” but it is illegal to bring seeds into the US and Customs will seize any cannabis seeds they find in packages or on a person.

Where can I buy cannabis seeds?

Many world-renowned seed banks are overseas in the Netherlands, the UK, Spain, and other countries where cannabis laws are less restricted. Seed banks provide seeds from a variety of different breeders.

In states with adult-use legalization or a medical marijuana program, you can buy seeds within your own state, either at a dispensary or through a specific seed company’s website.

Can you buy cannabis seeds online?

Before you purchase seeds online, you’ll need to figure out what strain you want to grow and what breeder you want to buy from.

Because US federal law still prohibits cannabis, it can be hard to find information on seed banks and breeders. Breeders who have a long history and positive reputation are usually a good place to start.

Check out our explainer and buying guide to cannabis seed banks for more info on buying seeds.

To get an idea of what well-established breeders look like, check out:

Europe

  • Sensi Seeds
  • DNA Genetics
  • Dinafem
  • Green House Seeds

US

  • Southern Humboldt Seed Collective
  • Exotic Genetix

You can also do some research and find an online grow journal that details the whole growing process of a specific strain from a particular breeder. Through these, you’ll be able to look over another grower’s specific notes and see pictures of the final results.

If you grow some seeds and like the results, try growing another strain from that same breeder and see how it goes.

Do dispensaries sell cannabis seeds?

Some dispensaries in medical and adult-use states sell seeds, but not all. Be sure to check or call ahead to see if they sell seeds. Buying marijuana seeds at the dispensary is far more straightforward, however, your options will be more limited than shopping online.

Dispensary staff should be able to give you information on the seeds they’re selling, but keep in mind that a lot of dispensaries focus on selling flower and end-products. It’s a good idea to call ahead and talk to staff to see if they are knowledgeable about seeds and can give you specific information on growing.

How to look for quality genetics when buying marijuana seeds

Breeders talk about “unstable genetics,” meaning that a seed’s origin is unknown. Make sure that when you buy a packet of seeds that it or the breeder who produced them can list where the seeds came from and how they were crossed and/or backcrossed to get the seed that you hold in your hand. If you can’t get a seed’s history, it could be anything and the result of poor breeding practices.

An inexperienced breeder might cross a male and a female one time and sell the resulting seeds as a new hybrid strain, but professional breeders usually put their strains through several rounds of backcrossing to stabilize the genetics and ensure consistent plants that reflect those genetics.

Which strain should I grow?

Even one weed plant can produce a lot of buds come harvest time, so make sure you grow a strain you like. Note strains you enjoy when you pick something up at the dispensary or smoke with friends, and look for seeds of it when you want to start growing.

Some strains are easier to grow than others because they are more resistant to mold and pests, so if you’re new to growing, you may want to try an easier strain to start.

Some strains also take longer to grow than others. Depending on whether you’re growing indoors or outdoors, you may want to grow a quicker marijuana strain if you live in a climate that get cold and wet early in the season. For example, indicas are known for having a shorter flowering time than sativas.

All of this information should be available to you when buying quality seeds.

What’s the difference between regular, feminized, and autoflower seeds?

Regular seeds

If you buy a packet of regular seeds, they’ll come with a mix of males and females. A lot of cultivators prefer to grow these because they haven’t been backcrossed—essentially inbred—as much as feminized or autoflower seeds. You’ll need to sex out the seeds once their reproductive organs show during the flowering phase and discard the males—because they don’t produce buds and will pollenate females, resulting in seeded flowers.

Feminized seeds

Seeds can come feminized, meaning you can just put them in soil and start growing for buds. These seeds are guaranteed to be bud-producing females and growing them cuts out the step of having to sex out plants and discard the males.

It also reduces the risk of having a stray male sneak into your crop—just one male can pollinate a huge crop, causing your females to focus their energies on producing seeds instead of buds.

Autoflower seeds

Autoflower plants change from the vegetative to flowering state with age, not the changing of their light cycle. They have a short grow-to-harvest time and can be ready to harvest in as little as 2 ½ to 3 months from when you put the seeds in the ground. The downside is that, typically, they are less potent, but autoflower seeds are great for people who want to grow cannabis but don’t want to spend a lot of time doing it.

How much do marijuana seeds cost?

Cannabis seeds usually come in a pack of 10 or 12 seeds and start at around $40 a pack and go up from there. Some high-end genetics can run between $200 to $500 a pack.

Feminized and autoflower seeds will cost more because more breeding work was put in to creating them and they take less time for the grower to get buds.

How many seeds should I buy? Are they all going to survive?

When you grow any amount of seeds, a percentage of them won’t germinate, even if you get them from a reputable breeder. Always count on a few not germinating or dying off, or roughly 1/4 of the total you put in the ground.

When growing regular seeds, some won’t germinate and some will have to be discarded because they’ll turn out to be males. With feminized seeds, some won’t germinate, but a higher percentage of them will turn into flowering plants because there won’t be any males.

If you want six total cannabis plants to harvest for buds and are growing from regular seeds, start with about 4 times as many, or 24 seeds. Some won’t germinate and some will turn out to be males, and then you’ll want to discard down to the six best phenotypes. If growing feminized seeds, you can probably start with about twice as many seeds in this case (about 12); a couple won’t germinate, and then discard down to the six best phenotypes.

Make sure to always stay within your state’s legal limit of growing plants.

How do I buy strain-specific cannabis seeds?

Strains like Blue Dream, Gelato, and Original Glue have gained in popularity in recent years. Check out these resources on how to buy these types of cannabis seeds:

So far, the medical use of cannabis is legal only in a limited number of countries, including Canada, Belgium, Australia, the Netherlands, the United Kingdom, New Zealand, Spain, and the U.S. states of California, Alaska, Hawaii, Maine, Nevada, Oregon and Washington, although the rest of the country is soon to follow. The use of cannabis plants for medical purposes can be done to make extractions or smoke the flower as is, due to the innate concentration of the different compounds in our medicinal strains.

What kind of Medical cannabis strain to choose?

Although the use of medical cannabis generally requires a prescription, distribution is usually done within a framework defined by local laws, although in countries like the United States and the Netherlands, patients have an allowance of cannabis plants they can grow freely.

Historically speaking, Medical Cannabis was used as the primary pain reliever until the invention of aspirin, it was also used to treat melancholia and migraines, as a sleeping aid, analgesic and anticonvulsant, although the latter is having a resurgence thanks to the benefits that have been found associated to CBD and the prevention of seizures.

Depending on your ailment, chose the right medication that suits in our Medical Cannabis section, higher in CBD for a longer physical effect and higher in THC for a longer lasting and stronger mental high.

Best Medical Cannabis Seeds For Home Growing

Medical marijuana can be a great resource for those suffering from a variety of different conditions. For many health ailments, it can offer the only source of relief. For the beginner who has never used cannabis or grown medical seeds before, the world of medical marijuana can initially seem overwhelming in all its variety. This guide will help you to choose the right strain of medical marijuana seeds for you. A basic understanding of the differences between strains can go a long way toward ensuring that you select one with the right properties to alleviate your specific symptoms.

When it comes to a strain’s effectiveness in treating your health concern, cannabinoids are of the utmost importance. The two main options for cannabinoids are THC (tetrahydrocannabinol) and CBD (cannabinol), with THC being the vastly more common type. A typical strain of medical cannabis may contain 15-20% THC while having only 1% CBD or less. THC tends to bind to neuro receptors in the brain, while CBD can affect receptors throughout the body. As a general rule, indica strains have high THC levels, and sativa strains have a high CBD level. The type you choose will depend largely on the symptoms you wish to treat.

Some of the unique effects of sativa strains include a mild hallucinogenic feeling, a sense of uplifting, and a boost in energy. For these reasons, sativa strains are best for use during the day. It can help ward off depression and increase the user’s focus and creativity. Sativa strains promote a feeling of well-being that puts people at their ease.

By contrast, indica strains are largely considered to be calming and relaxing, making them a great choice for nighttime use. It is very effective in treating several types of pain, including muscle soreness or migraine headaches. It can also relieve insomnia, stress, nausea anxiety, some seizures, and muscle spasms that come with multiple sclerosis or Parkinson’s disease. Indica strains are effective against a wide variety of health problems and are often the preferred choice of those battling cancer, HIV, or glaucoma.

There are many different hybrid strains available that offer the best of both worlds. They are available in both indica-dominant and sativa-dominant varieties, as well as fairly even splits. Hybrid strain users can have the pain relieving effects of Indica along with the wakefulness of Sativa for anytime use.

The effectiveness of medical marijuana does not come only from its cannabinoid levels and strain type- it also depends a lot on how it is being consumed. Results differ when users smoke the marijuana, consume it through edibles, or use vaporizers. To better understand what works for you and your condition, try out 3 to 4 strains using different methods, and keep a journal of what you took when, how much and how, and how you felt afterwards. These journal entries can be a great help to you, your doctor, and your medical marijuana provider in finding your most effective dose.
